VANCOUVER, BC--(Marketwired - August 30, 2017) - Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) announces that exploration drilling at the Guanaceví mine in Durango State, Mexico has extended high grade silver-gold mineralization along strike within the Santa Cruz vein and discovered new ore grade mineralization within a shallow, parallel splay of the Santa Cruz vein known as the La Negra vein.

These holes extend the boundaries of the current resource area (dated December 31, 2016). Drilling highlights include 786 grams per tonne (gpt) silver and 0.71 gpt gold (836 gpt AgEq) over 3.4 m true width (24.4 opT AgEq over 11.2 feet (ft)), with an internal interval assaying 2,260 gpt silver and 1.73 gpt gold (2,381 gpt AgEq) over 0.3 m true width (69.4 opT AgEq over 1.0 ft) (view long sections here).

Results for nine new drill holes are summarized in the table below.

Bradford Cooke, CEO of Endeavour Silver, commented, "These encouraging drill results continue to extend the resource envelope in the Santa Cruz vein at Guanaceví along strike from our current reserves and operating production areas. Another 15 drill holes have been completed and are in the lab for assaying. The 2017 drill program will wrap up this month below budget and ahead of schedule. We will then commence the process of the year-end resource and reserve estimation."
